DATING-STAMP.

Specification of Letters Patent.

Patented Feb. 10, 1914.

To all 'whom it may concern:

Be it known that I, THOMAS` R. Postr, a citizen of the United States, and residing at lVilmington, in the county ofNew Hanover and State of North Carolina, have invented certain new and useful Improvements in Dating-Stamps, of which the following is a specification,` such as will enable those skilled in the art towhich it appertains to make and use the same.

This invention relates to dating stamps of the class described and claimed in U. S. Letters Patent granted to me March 12, 1901, No. 669,661; and the object of this invention is to providea stamp of the class specified having improved printing devices, improved inking devices and improvements in the platen employed, whereby the construction of 'said stamp is rendered more simple and durable and less liable to get out of order, and whereby the operation thereof is rendered more simple and edectual; and with these and other objects in lview, the invention consists in a stamp -of the class specied, constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following Specication, of which the accompanying drawing forms a part, .in which the separate parts of my improvement are des.

ignated by suitable reference characters in each of the views, and in which Figure 1 is a sectional side view of my improved dating stamp; Fig. 2 a sectional plan view with part of the construction broken away and parts omitted; Fig. 3 a partial horizontal section on thel line 3-3 -of Fig. 1; Fig. 4 `a partial section on the line 4-4 of Fig. 1; Fig. 5 a artial section on the line 5-5 of Fig. 3; ig. 6 a plan view of a sheet of paper, showing the method of operation of my improved dating stamp; Fig. 7 a viewsimilar to Fig. 4, but showing a modification, and; Fig. 8 a section on the line 8-8 o f Fig. 7.

In "the practice of myinvention I provide an oblong casing a. comprising a top a2, ends a3 and a4 and sides a5 and affand for the purpose of this description the ends a3 and a4 will be called the front and rear ends, respectively, and"\\the sides aP and a, the right and left sides, respectively.

The casing a is provided at thetop of the rear end portion thereof with an upwardly directed support a7 on which is pivoted an arm the pivoted end of said armbeing provlded with ears b2 through which and said support is passed a pin b3, and one of the ears b2 is providedv with a forwardly directed projection bt from which is suspended a linkbli which passes through an aperture et8 in the top of the casing a.

' The front end of the arm b is provided with a head 0 which is approximately conical in form and provided at the top thereof with a supplemental head 02 forming a handle, and in the bottom of the head c is a conical recess 03 in which is loosely suspended a platen block c4 tothe bottom of which is secured a platen c5 of leather or other suitable material.

The walls of the conical recess o3 are conveX in vert-ical section and the walls of the platen block c4 are correspondinglyconcave in vertical section, and in the bottom central portion of said platen block is a vertical axial vrecess c and in the top thereof a corresponding bore or `passage c7, and a screw ci* is passed upwardly and through the recess c and through the bore o r passage 07 into the neck of the head c, whereby said platen block 'c4 is held in position, and the bore or passage 0"- is larger than the body of the screw cs and the recess c is greater in transverse dimensions than the head of said screw whereby said platen block is capable'of slight lateral movement, and the bottom part c9 of the conical head c and the bottom art c1 of the platen block o* are rectangu ar in form to prevent rot-ary movement of said block.

The bottom yof the top a2 of the casing a is provided directly under the head@a of the arm b with a recess a9 which opens upwardly through said top, and forwardly thereof, said top is provided with a transverse aperture a1 in which is mountedv a y roller d, and, rearwardly thereof with a transverse aperture a11 in which is mounted a roller d2. The top of the casing a is also provided on the opposite sides of the recess a9 therein with depending bosses or bearings a formed integrally therewith and between'which is a central vertical space a which ranges forwardly and backwardly and at the top of which is the recess a, and extending throu h the sides of said casing and through said bosses or bearings is a transverse bore or passage a14 Vin which is mounted a central transverse spindle f on the opposite end portions of which are mounted two sleeves g and h on which are mounted other sleeves i and j. The sleeve g is provided at its inner end with a year wheel g2 on which the years are represented by suitable type, and said sleeve is providedat its outer end with a circular disk or head g3 having a hub g4 onwh'ich the years are vprinted or otherwise placed, and

the disk or head g3 is provided with spacedV recesses 5 which correspond with the posi-l tion of tie ye rs on the hub g4 and on the wheel g2, and a spring finger g secured tothe bottom of the -corresponding boss or bearing am operates in saidl notches or recesses. Y

The sleeve h is provided at its inner end l with a day wheel 71,2 on which are placed or printed in suitable type, the days of the month, and at its outer end with a disk or head h3 having a hub it* on which the daysof the months are also printed or otherwise placed in positions which correspond withlv the positions of the days of the months onthe wheel h2, and the disk or head vh3 is also provided with spaced notches or recesses h5, anda sprmg finger h 1s securedto the bottom of the corresponding boss or bearing-af?L2 and operates in said notches or recesses.

The sleeve z' is provided at its inner end with a utility wheel 2 on which are printed or placed in suitable type, letters which represent' any desired word, or letters having a well-known meaning such as Act, 0. K., Pd or any other suitable words or type indicating certain words, and said` sleeve is provided at its outer endwith a circular ldisk `or head 3 having a hub i* on which are The sleeve j is provided at its inner end,

with a month wheel j2 on whichvthe months of the year are indicated in suitable type and said sleeveis rovided at its outer end with a circular dis or head js having a hub jt on which the months of the yearV are also placed, and the disk or head ja is also provided with spaced recesses i5, and a spring finger j is secured to the bottom of the corresponding boss or bearing a,12 and operates in said notches or recesses.

The wheels g2, h2, 2 and 7'2 are detachably connected with the corresponding sleeves g, h, andj by means of a tongue and groove construction as shown at c, and said sleeves and their correspondingwheels are independently rotatable as will be readily understood, this operation being performed by means of the heads of said sleeves, and the springs gs, h6, 6 and j prevent the accidental rotation of said parts without interfering with their movement when manipulated by hand.

In the tops of the bosses or bearings ai12 and on the opposite sides of the wheels g2, h2, 2 and y'2 is placed a removable signature die m and a removable business name die m2, and in the operation of the device as hereinafter described the platen 05 is adapted to bear on the said wheels and on the said dies. In the front bottom portion of the casing a and directly beneath the roller d is a similar transversey roller m, and in the back portion of said casing and rearwardly of and beneath the roller d2 is a transverse shaft n2 provided with a roller n3 andpat one end thereof with a ratchet' wheel n?, and the shaft n2 is provided at the corresponding y which o erates in connection with the ratchet W eel n4, and a spring ns is placed between the arm Z) and the top of the casing a and normally holds said arm in a raised position as shown in dotted lines in Fig. l, and each time that said arm is depressed and again raised to its normal position the roller n3 is turned through one step in the direc- ,tionl of the arrow .An endless inking strip or belt o is passed around the rollers d, d2, 'n and n3 and over the top plate of the casing beneath the platen vc5 and I also provide means for inking said `strip or belt, which comprises ashaft or'rod p mounted transversely of the bottom portion of the casing and on which are pivoted forwardly directed arms p2 provided at their e front ends with a transverse ink reservoir p3 1n which 1s mounted an mkmg roller p4, and

and one end of said spring passes beneath the front end portion ofthe arms p2 as shown at p and normally holds the-reservoir p3 and inking roller p4 in a raised position so that said roller will bear on the bottom of the roller n or on the strip or belt 0 as it passes beneath said roller. The other ends ofthe springs p5 are `passed beneath ba'ckwardl directed arms p7 also mounted on the sha t or4 rod p and between which is mounted a roller p8 which bearson the -bottom of t-he strip or belt o forwardly of the roller n3 and serves to take u any slack in said stri or belt and to distribute the ink thereon. ith this construction, as will be seen, each downward and upward movement ofthe arm b in the operation of the device, moves the strip or belt 0 in the direction of the arrow m2 one step, and the said strip or beltl is always kept thoroughly inked and in thoroughly operative'condition, but my invention is not limited to the use of the inking device herein shown and described,and the springs p5 are woundon the shaft or rod p sheet or may be made similar to a typewriter ribbon, in which eventv no inking device would be necessary.

The operation of my improved dating stamp is similar to that of other devices of its kind. A sheet of paper r is inserted over the printing wheels and beneath the platen c5 as shown in Fig. 1 and the arm b is forced downwardly in the usual manner, and -in this operation the business name, the month, .the day of the month, the year orany desired impression from the utility wheel together' with the signature are all printed thereon as shown in Fig. 6, the business name Belt Line in this case, being printed by the die m2 and the signature Jno. Jones in this case, being printed by the die m.

By means of my improvement as shown in Figs. 1 to 5, inclusive, I provide for the easy, simple and convenient manipulation of the printing wheels g2, h2, 2 and i2 from theopposite sides of the stamp by means of a construction which is positive in operation and the separate parts of which may be disconnected Whenever desired for cleaning, repairing or other purposes, and I also provide a simple and effective inking device, and by .mounting the platen c5 or the block c* with which it is connected so that said parts will have a slight swinging movement, I also provide for the exact operation of said platen at all times and insure the making of a per- -fect impression on the paper when said platen is depressed. I also provide means for throwing the inking roller pt out of operation when desired, and in the form of construction shown, these means consist of a pin 'r2 passed through one side ofthe lcasing a and provided at its outer end withJ a head 7'3 by which it may be manipulated, and at its inner end with a cam head 9* on which one of the arms p2 normally bears, and by turning the pin r2 so as to throw the cam head 1'* into operation, the reservoir p3 and roller may be depressed into the position shown in dotted lines in Fig. 1.

In Figs. 7 and 8 I have shown a modification in which the printing wheels g2, h2, 2 and 7'2 may be manipulated from one side of the stamp. With this construction, a spindle s is employed, which is mounted in one side of the stamp, only, and projects from said side, and a year wheel t, a day wheel u, a 'utility wheel v anda month wheelfw are substituted for the corresponding wheels g?, h2, 2 and `7'2'shown'in Fig. 4. The utility wheel fv is secured to the innerA end of the spindle s and .said spindle is provided at its outer end with a' disk v2 on.wh1ch the characters, letters or words similar to those on the wheel v are formed or placed. The Wheel' t is connected with a sleeve t2 mounted on the spindle s and provided lat its outer end with a disk t3 on which numerals representing the years are formed or placed. The wheel u is'connected with a sleeve u2 mounted on the sleeve t2 and provided at its outer end with a disk ug on which are placed or formed numerals representing the days of the months, and the wheel w is connected with a. sleeve 'w2 mounted on the sleeve u2 and provided at its outer end'with a disk 'w3 on,

which are printed, placed or formed letters representing the months. It will be understood that the characters, letters or numerals on the disks 02, t3, us and w3 correspond with It will be understood that the operation l ofthe stamp, with the construction shown in Figs. 7 and 8 will be the same as that shown in Figs. 1 to 5, the only difference be.- ing in the method of operating the printing wheels from one side of the stamp instead of from both sides and the construction by which this operation is:` performed, and in the operation of the spring fingers fj* in connection with the hubs formed on the printing wheels.

The arm b is provided at its pivoted end with. a downwardly directed stop b which operates in connection with the upper back corner of the .casing a to limit the upward movement of said arm as shown in dotted lines in Fig. 1, and in the manipulation `of the stamp, the supplemental head c2 may be struck by the hand in the usual manner to depress said arm, or said supplemental head may be grasped in the hand and the arm b forced downwardly.

` My invention is not vlimited to any particular form of the casing a, the construction thereof or the material-employed, and

various changes in and modications of the operative parts of my improved stamp as herein shown and described may be made,

within the scope of the appended claims,I

without departing from the spirit of my invention or sacrificing -its advantages, and I reserve the right to make all such alterations therein as clearlyl come within the scope of the invention 785,204, the said application being a division of this application.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is A- 1. In a dating stamp the combination with printing devices, of a pivoted arm, having a head provided on the under side with a polygonal platen receiving recess, theA upper portion of said recess forming a bearing portion, an integral polygonal Iplaten smaller than but corresponding in shape to said recess, and located within thesame, said platen having a bearing portion engaging the bear'- v ing portion of the recess, and means for connecting the bearing portions' of said recessl and platen, permitting the movement of the platen with respect to the head within the Y limits of said recess, whereby the rotary movement of the platen with respect to the head is prevented.

2. In a dating stamp the combination with printing devices, of a pivoted arm, having a head provided on the underside with a polygonal platen receiving recess, the upper portlon of said recess forming a bearlng por tion, and an lintegral 'polygonal 'platen of corresponding shape to but smaller than said recess and located within the same, having a bearing portion engaging the bearingdportion of the recess, and being provided with a vertically disposed aperture extending through said bearing portion, and alsecuring screw vpositively and rigidly secured to the head and having a portion of less diameter than said aperture, extending therethrough and provided with a head for directly engaging the platen whereby said platen is prevented from turning with respect to the head but is permitted a rocking movement withrespectthereto without the interposition of yielding devices.

3. In a datingv stamp the combination with a frame having a recess therein and a horizontal bearing aperture located on either side of the same, and communicating therewith, of a plurality of typewheels located in said recess, a central shaft extending through said bearing apertures, a plurality of sleeves extending through said bearing apertures, a key detachably connecting each of said wheels with one of said sleeves, and

preventing relative rotary movement between them when in engagement, but per-v mitting the longitudinal withdrawal of the sleeves, and means connected with said shaft for holding said sleeves from longitudinal movement 1n said bearing apertures without interfering with the rotary movement thereof.l

In testimony' that I claim the foregoing as my invention I have signed my name in presence ofthe subscribing witnesses this 4th day of December 1911.
